I To all whom it may concern:

Be it known that l, (Emerson K. Bani WIN, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for Quenching Coke, of which the following is a specification.

This invention relates to apparatus for quenching coke; my object being to provide an apparatus of simple and eflicient construction and operation whereby hot coke, immediately after its discharge from the ovens, is rapidly and thoroughly quenched with a minimum volume of water; whereby excess moisture is eliminated from the coke, and whereby such coke, in a relatively cool and dry state, is directly delivered to a suitable conveyer.

The invention, in its preferred form of embodiment herein illustrated, comprises a rotary coke-conveying platform which is so mounted and arranged in respect to the ovens that the platform can be readily positioned to receive the coke from any predetermined oven ovens; means for rotating the platform whereby the coke is well distributed thereon; means for subjecting the progressing coke, in a part of its path, to the influence of a quenching liquid, and means in another part of such path for discharging the then relatively cool and dry coke from the pla form. Underlying the platform, adjacent the quenching zone, is a pan or trough into which the liquid drains from the coke, andoverhanging the platform and its contents is a protective hood having an appropriate steam and fume outlet leading to a suitable point of discharge.

The invention also comprises novel features of construction and combinations of parts which will be hereinafter described and claimed.

In the drawings- Figure 1 is a plan of a coke quenching apparatus embodying a preferred form of my invention; the front of the ovens being shown.

Fig. 2 is a side elevation of the apparatus, part of the hood being broken away.

Fig. 3 is a transverse vertical section through the apparatus and the discharge openings of the adjacent ovens, as on the line 3-3 of Fig. 1.

Fig. 4 is a horizontal section of the apparatus, as on the line 4-4 of Fig. 3.

. Fig. 5 is a sectional-detail showing the defleeting plate, and adjuncts.

Fig. 6 is a perspective view of the delivery conduit, the pivoted shelves or chutes thereof being omitted.

Referring to the drawings, 10 designates coke ovens arranged in vertical rows as usual. in front of and below the discharge openings of the ovens is arranged a suitable frame structure 11 on which the rails 12 of a track are supported.

On the rails are mounted the wheels 13 of a car which may be moved in front of any vertical row of ovens as desired. The car preferabl comprises an iron frame including stan ards 14, and longitudinal and transverse beams 15,16, respectively, all being suitably arranged and bolted together. to provide a rigid structure of appropriate shape and size for its intended purpose. Supported on the car frame, by bars 17, for example, depending from the upper beams, is a sheet metal hood including a partial cylindric shell 18 and a roof 19. One end of the shell is located beyond the side of the car frame adjacent the ovens, and is secured, as at 20, to the adjacent vertical wall 21 of an upright trough-like conduit 22 into which the hot coke may be discharged from the ovens, as will presently appear. The other end of the shell terminates short of the opposite vertical wall ofthe conduit, as at 23, so as to alford an open or unconfined space above the track, as seen most clearly in Figs. 1 and 4. 7

Theconduit is of suflicient length to extend vertically in front of any row of ovens. It is open at its upper and lower ends, its

back 24 and the side wall 21 being cut away at the bottom, as at 25, to afiord an open discharge space. A suitably-disposed pipe 26 connects the up er rear art of the conduit with a centra stack 2 rising. from a perforated cover plate 28 supported on the car frame; and a pipe 29 also connects a flaring or dome-like chamber 30 in the roof of the hood with the stack, said chamber being located directly above the quenching zone hereinafter referred to. By the pipe connections just described the fumes and hot gases from coke delivered-to the conduit from the ovens, and also the steam evolved within the hood during the quenching of the coke therein, are conducted to and discharged by way of the stack. The conduit is equipped with spaced-apart shelves or chutes 31 ada ted to be positioned in proiimity to the ottoms of the respective ovens of any of the rows preparatory to the discharge of the coke from the ovens. In the present instance the shelves or chutes are supported on horizontal rocker-bars 32 which are pivoted at their ends in the side walls of the conduit. The trunnions of the bars project beyond one side of the conduit and are equipped with crank-arms 33 which are flexibly connected together and to one arm 34 of a hand lever 35 by means of chains 36, for example. The hand-lever is fulcrumed to a' suitably-disposed post 37 on the framework of the car, so that by proper manipulation of the lever the shelves or chutes 31 can be simultaneously rocked on their hearings to raise or lower the shelves or chutes, as desired. These shelves or chutes are raised preparatory to the moving of the car alon the track, thus permitting them to clear he front projections of the ovens. When the caris located with the conduit thereof in front of a row of ovens the shelves or chutes are lowered in order that the contents of any oven or ovens of the row may be pushed on the shelves or chutes and directly thereby into the conduit. A rotary coke-conveying platform is mounted and arranged to underlie the hood and the conduit in such a manner as to receive the hot coke delivered into the conduit from the oven or ovens. This platform preferably comprises an outwardly and downwardly inclined annular bed 38 having a peripheral guard rim 39 and an inner upstanding cylindrical wall 40, the upper surface of the bed having a protective covering of fire brick 41 or other refractory material. The bed is secured to and supported by a spider 42 fast to the foot of a central supporting shaft 43 which is mounted to rotate in suitable bearings 44 in a cylindrical supporting body 45 fixedly secured to and carried by the framework of the car. The cylindrical body 45 and wall 40 are in spaced concentrlc relation to each other and are provided with spaced-apart annular flanges 46, 47, respectively, constituting tracks. Between these tracks are interposed a series of anti-friction wheels 48, the shafts of which are preferably journaled in and between a pair of concentric rings 49 encircling the body 45. Hence the platform is uniformly supported by and freely rotatable on the stationary body 45.

Surrounding the top of the wall 40 is a trough 50 adapted to contain water or other sealing liquid into which depend flanges 51, 52 formed respectively on the inner peripheral edge of the roof of the hood and on an annular plate 53 secured to the reduced upper portion of the stationary bod 45. Thus is provided a li uid seal, whic serves effectively to preclu e the esca e of steam around the inner ortion of the 00d roof in the re 'on of t e quenching zone. Such steam, ing evolved during the quenching operation, rises through the pipe 29 to the stack, as previously mentioned.

Any suitable means for rotating the platform may be employed. In the present instance the upper end of the shaft 43 has fast thereon a worm wheel 54 with which meshes a worm 55 on a driven shaft 56 whereby the inclined annular bed can be slowly rotated in a path beneath the hot, coke fed through the conduit 22, and such coke thus be well distributed on the rotating bed. The shaft 56,- which has its bearings supported on the car frame, is provided at one end with a bevel gear 57 in mesh with a similar gear 58 on a cross-shaft 59 which also has its bearings on the car frame. The shaft 59 is operatively geared with a motor 60 at one end of the frame, and is rovided with a loose sprocket wheel 61 whic is connected by a sprocket chain 62 with a sprocket wheel 63 on one of the car axles. Both shafts are provided with suitable clutches 64, 65, respectively, by the operation of which the shaft 56 and the sprocket wheel 61, or either of them, can be rendered active or idle as desired.

When the car, by actuation of the motor, is run along the track to a position in front of a row of ovens, the clutch 65 is manipulated to unclutch the sprocket-wheel 61, and the clutch 64 is operated to establish the worm shaft connection with the motor.

Thereupon the coke-conveyingplatform is rotated counter-clockwise and the coke is delivered thereto from the adjacent oven or ovens by way of the conduit 22. Hence the falling coke is well distributed on the travelingsurface of the platform. The coke thus distributed is progressively carried under the hood and immediately subjected to the quenching operation. The quenching devices preferably comprise a series of water spraying pipes 66 which are located within the upper part of the hood and adjacent the conduit, and are connected to a common water supply pipe 67. Thus the coke as rapidly as it is carried from the conduit by the platform is subjected to the quenching influence of the water, and by reason of the strewn condition of the coke a relativel small amount of water is required to e ect the uniform and thorough quenching thereof.

Preferably the platform is partially en circled by the rim of a segmental pan or trough 68 which underlies the platform and is supported by brackets 69 depending from the shell of the hood. This trough extends from the wall 21 of the conduit to a point well in advance of the quenching zone, and is so arranged that the water directed upon and flowing from the coke is discharged over the .peripheral rim of the incl ned bed and into the pan or trough during the travel of the distributed mass of coke in a path at and for an extended interval be 0nd the re gion of the quenching zone. In t e continued progress of the coke on the platform such coke is freed from excess moisture, and is finally discharged from the platform at the opening of the hood above the platform. The means for thus dischar i the coke comprises preferably an a ar y-disposed deflecting plate which overhangs the path of the platform, said late depending in close relation to the plat orm and being supported by bars 71 afiixed to the framework of the car. When the progressing coke impinges against the opposing angular face of the plate such material is pro ressively defiec outwardly of'and disc arged from the platform, falling thence into the space between the rails'u on which the wheels of the car are moun Suitabl arranged to run between and parallel wit the rails is the upper run of a conve ing belt 72 which directly receives the falling coke from the platform, and transports it to a suitable location for storage, or other purpose.
